Hippo signaling is a highly conserved pathway central to diverse cellular processes. Dysregulation of this pathway not only leads to developmental abnormalities but is also closely related to the occurrence and progression of various cancers. Recent studies have uncovered that, in addition to the classical signaling cascade regulation, biomolecular condensates formed via phase separation play a key role in the spatiotemporal regulation of Hippo signaling. In this review, we provide a summary of the latest research progress on the regulation of the Hippo signaling pathway by phase separation, with a particular focus on transcriptional activation mediated by Yes-associated protein (YAP)/transcriptional coactivator with post-synaptic density-95, disks-large, and zonula occludens-1 (PDZ)-binding domain (TAZ) condensates. Furthermore, we discuss the utility of chemical crosslinking combined with mass spectrometry to analyze the TAZ condensate interactome and examine the role of the protein fused in sarcoma (FUS) in modulating the biophysical properties of TAZ condensates, which in turn influence their transcriptional activity and pro-tumorigenic functions. These insights not only advance our understanding of Hippo signaling but also offer new perspectives for therapeutic interventions targeting diseases linked to dysregulated YAP/TAZ activity.

The bioactivity-guided isolation of potentially active natural products has been widely utilized in pharmaceutical discovery. In this study, by screening fungal extracts against coxsackievirus B3 (CVB3), three new aspochalasins, templichalasins A‒C (1‒3), along with six known aspochalasins (4‒9) were isolated from an active extract derived from the endophytic fungus Aspergillus templicola LHWf045. Compound 1 features a unique 5/6/5/7/5 pentacyclic ring system, while compounds 2 and 3 possess unusual 5/6/6/7 tetracyclic skeletons. Their structures were characterized through extensive spectroscopic analyses, electronic circular dichroism (ECD) calculations, and single-crystal X-ray diffraction analysis. Additionally, we demonstrated that compound 4 can be readily converted into compounds 1‒3 under mild acidic conditions and proposed a plausible mechanism for this conversion. Bioactivity evaluation of compounds 1‒9 against CVB3 revealed the inhibitory effects of all compounds against the virus. Notably, compound 9 exhibited superior antiviral activity, surpassing the commercial drug ribavirin in selectivity index (SI) value.

Objective:To explore the clinical utility of peripheral immune-inflammatory markers in predicting late-life depression with cognitive impairment(LLD+ CI + ). Methods:A cross-sectional study was conducted between January 2020 and December 2021, collecting demographic data, peripheral blood inflammatory markers, and cognitive function scores from 40 patients with LLD+ CI + , 38 patients with late-life depression without cognitive impairment(LLD+ CI -), and 26 healthy controls(HCs). Logistic regression analysis and receiver operating characteristic(ROC)curve analysis were employed to assess the value of peripheral blood inflammatory markers in differentiating LLD+ CI + . Results:Patients with LLD+ CI + exhibited significantly different levels of lymphocytes, C-reactive protein(CRP), systemic immune-inflammation index(SII), systemic inflammation response index(SIRI), neutrophil-to-high-density lipoprotein cholesterol ratio(NHR), and neutrophil-to-lymphocyte ratio (NLR)compared with the LLD+ CI - group and the HGs group( F=4.000, 11.642, 13.541, 10.441, 6.623, 4.193; P=0.022, 0.003, 0.001, 0.005, 0.036, 0.018). The multivariate logistic regression analysis of factors influencing LLD+ CI + revealed that elevated levels of CRP( OR=4.933, 95% CI: 1.385-17.563, P=0.014), SII( OR=5.534, 95% CI: 1.336-22.927, P=0.018), and NLR( OR=3.386, 95% CI: 1.470-7.797, P=0.004)constitute risk factors for geriatric depression with cognitive impairment, while an increased lymphocyte count( OR=0.206, 95% CI: 0.058-0.725, P=0.014)serves as a protective factor.Further analysis identified CRP, lymphocytes, SII, and NLR as significant predictors for LLD+ CI + , with areas under the curve (AUC) values of 0.849(95% CI: 0.760-0.934), 0.847(95% CI: 0.761-0.933), 0.860(95% CI: 0.777-0.943), and 0.857(95% CI: 0.777-0.938), respectively, in distinguishing LLD with or without cognitive impairment. Conclusions:Peripheral immune-inflammatory markers represent an economical and effective approach for investigating the pathophysiological changes and predictive factors associated with LLD+ CI + .These findings provide valuable insights into the underlying mechanisms and potential therapeutic avenues.

Malignant tumors(commonly referred to as cancer)represent a major global public health challenge and contribute significantly to the worldwide disease burden.Early screening plays a critical role in improving detection rates,enabling timely intervention,and enhancing pa-tient survival rates.However,current cancer screening guidelines primarily focus on site-specific screening,which may not fully address the need for comprehensive early detection.A scientifical-ly rational,multi-cancer screening approach offers several advantages:it optimizes the use of bio-logical samples,reduces time costs for participants,enhances the efficiency and comprehensive-ness of screening,and minimizes overall expenses.Such an approach also facilitates the rational allocation of healthcare resources,ultimately helping to reduce the societal burden of cancer.To address this need,the Cancer Epidemiology Committee of the Chinese Anti-Cancer Association has developed the Expert Consensus on Combined Screening for Common Cancers in China.This consensus integrates multidisciplinary expertise and synthesizes the latest domestic and interna-tional researches on cancer screening,early detection,and treatment for prevalent malignancies.Drawing upon China's unique demographic and healthcare context,as well as practical screening experiences,the consensus provides evidence-based recommendations on target populations,screening technologies,and procedural workflows for multi-cancer screening.These guidelines align with the principles and methodologies established by the World Health Organization(WHO),aiming to:enhance the effectiveness of combined cancer screening in China,improve early detec-tion rates,and provide a scientific foundation for national cancer prevention and control strategies.

Objective:To compare the effect of transcranial magnetic stimulation (rTMS) of the contralesional hemisphere at different frequencies on the recovery of upper limb motor function after a moderate-to-severe ischemic stroke.Methods:The inter-hemisphere compensation model was applied along with electroencephalogram (EEG) power spectrum density measurements. Thirty stroke survivors were randomly assigned to a sham stimulation group ( n=9), a high-frequency stimulation group ( n=11) or a low-frequency stimulation group ( n=10). In addition to physical and pharmacological therapy, the low-frequency and high-frequency groups received 1Hz or 5Hz rTMS, while the sham group received sham stimulation. The rTMS was delivered over the contralesional (unaffected) hemisphere once daily for 20 minutes over 15 consecutive days. Before, as well as 7 and 15 days after the treatment, all of the subjects′ motor functioning was assessed using the Fugl-Meyer Assessment for the upper extremity (FMA-UE) and their ability in the activities of daily living was assessed using the modified Barthel Index (MBI). Resting-state EEGs with the eyes closed were also recorded, and absolute alpha power across the whole brain was calculated. Changes from baseline FMA-UE and MBI scores and absolute alpha power were analyzed using one-way and repeated-measures analysis of variance. Results:After the treatment, significant within-group improvements from baseline were observed in the FMA-UE scores, MBIs and absolute alpha power, except for absolute alpha power in the low-frequency and sham groups. The repeated-measures analysis of variance revealed significant time × group interactions for FMA-UE ( F=9.926, P≤0.001), MBI ( F=8.789, P≤0.001) and absolute alpha power ( F=4.511, P≤0.05). So the treatment effects varied among the groups. Post hoc Bonferroni-corrected comparisons showed that the high-frequency group exhibited significantly greater improvements from baseline in terms of all three indicators compared with the other two groups. Conclusions:High-frequency (5Hz) rTMS applied to the contralesional hemisphere produced greater improvement than low-frequency (1Hz) stimulation in the upper limb motor function of patients with moderate-to-severe stroke. These findings support the use of the interhemispheric compensation model to guide rTMS therapy, particularly for patients with FMA-UE scores below 43.

Objective:To investigate the accuracy and clinical utility of a newly designed acetabular bone defect classification system based on the ischial-gluteal pillar in assessing the severity of acetabular bone defects and guiding hip revision surgery.Methods:A retrospective analysis was conducted on 474 patients who underwent hip revision surgery for prosthetic loosening after total hip arthroplasty at our institution from January 2010 to December 2020, including 296 males and 178 females with a mean age of 70.4±8.9 years (range: 52-86 years). The accuracy of our classification system in guiding surgical procedures was evaluated by comparing preoperative defect classifications with intraoperative findings. Clinical outcomes were evaluated using preoperative and final follow-up Harris hip scores (HHS) and Oxford hip scores (OHS), as well as the incidence of complications.Results:Preoperative classifications included 143 Type I, 192 Type II (Type IIa: 86 cases, Type IIb: 59 cases, Type IIc: 47 cases), 93 Type III (Type IIIa: 54 cases, Type IIIb: 27 cases, Type IIIc: 12 cases), and 46 Type IV cases (Type IVa: 32 cases, Type IVb: 9 cases, Type IVc: 5 cases). Compared with intraoperative findings, classification accuracy was 99.3% for Type I (1 errors), 98.4% for Type II (3 errors), 97.8% for Type III (2 errors), and 97.8% for Type IV (1 misclassified as Type III). The mean follow-up was 5.8±4.4 years (range: 2-12 years). At final follow-up, mean HHS improved from 36.65±10.27 to 91.36±7.53, and mean OHS increased from 11.35±4.36 to 44.6±5.27 with significant difference ( P<0.001). Complications included one Type IV periprosthetic infection, one Type II hip dislocation, one Type I and two Type IV re-revisions (due to femoral loosening or graft resorption), one Type II and one Type III death unrelated to surgery, and one Type I postoperative thigh hematoma. No neurovascular injuries occurred. Conclusions:This novel 3D acetabular bone defect classification system, based on ischial-gluteal pillar integrity, provides accurate preoperative assessment and effectively guides surgical planning. Its application demonstrates favorable mid-term outcomes in hip revision surgery.

Objective:This study aimed to analyze the expression of B-cell maturation antigen (CD269) on myeloma cells in patients with newly diagnosed multiple myeloma (NDMM) and evaluate its prognostic value.Methods:The retrospective analysis was conducted on the clinical data of 154 NDMM patients admitted to the outpatient clinics and wards of Beijing Chaoyang Hospital, Capital Medical University from October 23, 2018 to December 25, 2023, including 90 males and 64 females, aged 60(55,66) years old. CD269 phenotype was analyzed using flow cytometry (FCM). Specifically, patients were divided into CD269 positive group (expression>20%, n=103) and CD269 negative group (expression≤20%, n=51) based on the flow cytometry prior to treatment. Initially, we assessed the effect of CD269 expression on progression-free survival (PFS) in patients with NDMM and compared the two groups. Through a cross-sectional analysis, we examined the basic clinical characteristics, 32 laboratory indicators, and 5 cytogenetic indicators. We identified differences between the two groups and analyzed the impact of various indicators on the PFS of patients in both the CD269 positive and negative groups. Furthermore, we employed the Cox proportional hazards regression model to evaluate the influence of CD269 expression and other disease-related indicators on patients′ PFS. Results:Among 154 NDMM patients, 103 were identified as CD269 positive (66.9%), while 51 were CD269 negative (33.1%). No statistically significant differences in clinical indicators were observed between the two groups. The PFS for CD269 positive group was significantly lower than it in the CD269 negative group [28.0(18.0,41.0) months vs 35.0 (27.0, -) months, HR=2.012, 95% CI 1.059-3.824, χ 2=4.554, P=0.033]. Cox proportional hazards regression analysis indicated that CD269 positivity and non-IgG subtypes were independent risk factors influencing PFS in NDMM patients( HR=2.395,95% CI 1.152-4.979, P=0.019; HR=0.425,95% CI 0.223-0.810, P=0.009). In the CD269 positive group, progression-free survival (PFS) was significantly shortened in patients with>65 years, non-IgG subtypes, International Staging System (ISS) stage Ⅲ, β2-microglobulin (β2-MG) levels≥5.5 mg/L, abnormal t(11;14) or ≥3 cytogenetic abnormalities. Conclusion:CD269 positivity serves as an independent risk factor influencing PFS in NDMM patients. Among the factors examined, older age, non-IgG subtype, ISS stage Ⅲ, elevated serum β2-MG, the presence of an abnormal t(11;14) translocation and≥3cytogenetic abnormalities, significantly impact the PFS of CD269 positive patients.
